Guards your equipment from overvoltage
damage.
Offers local or remote
control.
Provides enhanced
Web-based device
setup and control
management.
Test and optionally
power cycle a
connected host using
auto ping.
Send e-mail alerts of
impending power
shutdown to up to
three designated
recipients.
I
f you power on a large amount of
file servers and networking
equipment all at once, chances
are that the input AC current will
be too much for the power
transformer. Ideally, the equipment would power on at specified
time intervals to reduce the power
load at any given time.
The Intelligent Power
Manager protects your equipment
from damage caused by excess
power voltages generated when
powering on several loads at the
same time. It powers on or off any
or all loads in any sequence over
a wide range of time intervals. A
circuit breaker at the AC input
provides overall protection. And
the Power Manager features a
power-on current limit that
prevents the circuit breaker from
tripping during power on. It
continuously monitors input line
Remote power management protects your
networking equipment from power current damage.
Key Features
INTELLIGENT POWER MANAGER
voltage, total load current, and
line frequency.
Two models are available. The
PS540A has eight NEMA 5-20R
power outlet connectors and one
120-VAC IEC power input connector. The PS545A has eight NEMA
5-20R power outlet connectors
and two 120-VAC IEC power input
connectors.
Total load capacity is 20 amps
for the single-input model and 40
amps for the dual-input model.
Since the Power Manager
reduces the input current, it limits
potential equipment damage
caused by excess voltages
generated when powering on
several loads at the same time.
Operate and control the
Power Manager either locally or
remotely. Locally, a front-panel
pushbutton switch and a backlit
LED status indicator let you select
power-on or off sequences.
Remotely, use a PC or other
computing device accessed
through the Intelligent Power
Manager’s RS-232 or RS-485
console port. Its male or female
RS-232 DB9 console port is on the
manager’s front panel. Its RS-485
RJ-11 connector is on the
manager’s back panel. The
selected connector attaches to a
laptop computer, desktop
computer, or palm pilot.
The power manager also has
a Web/Telnet option that’s
accessed through its front-panel
RJ-45 connector. Web features
include device setup and control
management. Telnet features
include auto ping for testing, and
power cycling, as well as e-mail
alerts for power shutdown.
